Abstract:

Study was conducted to evaluate the effect of enhanced level of nutrition on nutrient intake and microbial protein (MBP) production of two genotypes; Deoni and HF crossbred calves. Treatment groups of Deoni (DTG) and HF crossbred (XTG) were fed 30% more protein and energy as compared to their respective control groups (CGs). Dry matter intake (DMI) of DTG was reduced by 18% in comparison to DCG. Crude protein (CP) intake in DTG was 312 g/d and was higher by 14% compared to DCG. Whereas, CP intake in XTG was 38% more compared to XCG. Gross energy (GE) intake by DTG was 8.13 Mcal/d compared to 9.70 Mcal/d of DCG. The MBP production in XCG, XTG, DCG and DTG was 239, 229, 143 and 142 g/d, respectively. Quantitative availability of MBP was constant and related to size of the calf. This indicated that the DMI in Deoni calves was regulated by the nutrient density of diet indicating towards the low level of phenotypic plasticity of digestive system in Deoni calves providing less scope for productive improvement by nutritional intervention compared to HF crossbred calves.
